MOTOR.

SPECIFICATION forming part of Letters Patent No. 445,593, dated February3,1891.

Application tiled November 4, 1889. Serial No. 329,142. (No model.)

. such as Will enable others skilled in the art to which it appertainsto make and use the same.

Myinvention relates to motors such as are operated by steam, gas,compressed air, &c., andhas for its object to provide a device of thisdescription which shall operate with very little friction and be capableof exerting considerable power.

Iith these ends in view myinvention consists in the details ofconstruction and comhereinafter set forth, and then specificallydesignated by the claim.

In the accompanying drawings, Figure lis a perspective representingmyirnproved m0- tor Wit-h the cap and front cheek-plates removed; Fig.2, a central vertical'longitudinal section; Fig. 3, a detail interior ofthe front cheek-plate; Fig. et, an interior view of the casing with themotor-Wheel removed; Fig. 5, a central vertical crosssection of myimproved motor; Fig. 6, a back view of the easing with the rearcheek-plate removed.

Similar letters denote like parts in the several figures of thedrawings.

A is the casing, which is closed at the rear and open at the front.

B is a cap which fits snugly within the front of the casing, so as toform the front Wall thereof, and C is the 1notor\vheel rigidly mountedon the shaft I), the Wheel being Within the casing and inclosed by thecap I3, while the shaft is journaled within the cap and the frontcheek-plate, to be hereinafter described. The diameter of this Wheel isless than the interior diameter ofthe casing, so that there is a space abetween the periphery of said Wheel and the casing.

Within the front and rear faces of the wheel are equidistantWedge-shaped pockets E, which are preferably ve in number, and

are arranged radially from the axis of the wheel.

The interior faces of the back Wall of the casing and` of the cap areeach provided with equidistant pockets F, similar to the pockets E, butextending in assembled position in a direction reverse to that of thelatter. These pockets F are preferably three in number, and in front ofeach of them are ports ZJ, which extend through said back Wall and cap.Between said pockets F are channels G, which extend radially beyond saidpockets and also beyond the circumference of the wheel C.

H I are the front and rear cheek-plates, respectively, Within the innerfaces of which are formed annular channels J, with which the ports bcommunicate. These channels have ducts K, which lead to and communicateWith the steam-box L, which extends through the foot of the casing fromside to side, and is supplied directly from the steam-pipe M.

N are adjusting screws, which extend through the front plate II Withinthe cap B,

and by means of which the latter may be adj usted to a position in closeproximity to the Wheel C Without exerting any friction thereon.

O is the exliaustport,whieh extends through the base of the casing andopens into the interior of the latter, as seen at P. Q are bolts whichsecure the casing and cheek-plates together.

The operation of myimprovement is as follows: Steam enters through thepipe M Within the annular channels J in both plates ll I, and thencethrough the ports l) to the Wheel. The steam will impart motion to theWheel by entering one of the pockets E and expanding against theinclined ivall thereof, and as the wheel revolves the steam willsuccessively operate on all the pockets E through the ports b, thusimparting a rapid revolution to said Wheel. This will be readilyunderstood when it is borne in mind that the pockets E in the Wheel andthe pockets F in the inner, front,

IOO

as to drive the wheel. As the wheel revolves, the steam in the pockets Ewill he discharged to the space a, and thence be exhausted through theopening P.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the casing` having` the exhaust-port O, thesteam-chest L, and the annular channels J, the Wheel mounted in thecasing and of a less diameter, thereby into the channels G, whence itwill find access
